In this article, we have explored how to parse json files on the linux command line with jq. we have covered the basic syntax of jq query expressions, as well as more advanced features such as filtering, array manipulation, and combining filters and transformations. Sometimes i need to read multiple string values from json, and save them into their own variables as a pre processing step. assigning multiple variables in bash using process substitution, i.e., <(command) and using join with an empty string saved the day.
